Application filed September weighing scales, and particularly to means for retaining themupon the spiders on which they are supported, and one of the principal objects is to providea simple and reliable device of thischaracter which is so applied as to leave the uppersurface of the platter smooth and free from openings.

1 Another object is the provision of a de' Vice of this kind ca'pabl'eof being used with platters made of material ofsubstantially uniform thickness throughout and free from bosses and openings. g

Another object is the provision of a re taining device for platters, which will at all times be resiliently forced into engagement with the platter to prevent the abnormal displacement thereof.

Still another object is to provide a device of this character whereby the removal and replacement of the platter may be made without the use of special tools.

Other objects and advantages will be apparent from the following description, in Which reference is had to the accompanying drawings illustrating a preferred embodiment of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawings r c Figure I is a frontelevational view of a weighing scale embodying my invention;

. Figure II is a top plan view of a spider equipped with means for holding the platter in place, the position of the platter on the spider being indicated in dotted lines;

Figure III is an enlarged fragmentary vertical sectional view through the platter and retaining device; and V Figure IV is an enlarged fragmentary ele" vational View of the retaining device of my invention.

load counter-balancing and indicating mechanism contained therein.

The lever B carries a platform spider 6 which is formed with a plurality of arms 28; 1925. seriai- N01. 58,969.

( refer-21151 8: four) 7,; 8 ,9 and 10 extending outwardly for-the purpose of supporting the platter ll in substantially horizontal position. My invention relates" particularly to the platter 11' and to the means for holding 1t in plac'e upon the spider 6.v

Tlifeiextremities' of the arms 9uand 10 are provided with bosses '12, the upper surfaces of thebosses preferably lying-in the same plane, so as to properly engage and support the platter 11', the platter being'provided with a downwardly and inwardly extending flange 13 which hooks over the ends of the arms9 andlO; -;Thespider 6 .isalso, formed with arearwardlyprojecting bifurcated portion114 to which is secured a member 15, the latter having a bore adapted to slidably receive a plunger 16, the outer end of the plunger being beveled so as to wedgingly engage the flange 13 of'the platter 11. The inner end of the plunger 16 is provided with a bore within which is reposed an expansive coil spring 17 the purpose of the spring being to constantly urge the plunger 16 into engagement with the flange on the platter.

lVhen it is desirable to remove the platter the downwardly projecting ear 18 forming an'integral partof'the plunger 16 may be moved rearwardly, thus disengaging the ilirnge 13 and the beveled end of the plunger In order to prevent an abnormal derangement ofthe plunger 16 and spring 17, a stop member 20 is secured to one end of the member 15 by means of a screw 21 and is adapted to be engagedby the ear'18 under the influenceof the spring 17 whenever the platter is removed fromthe spider. Then the platter is in proper position upon the spider 6 the plunger engages the flange 13 and the ear 18 is thus prevented from engaging the stop member 20, as clearly illustrated e in Figure III.

The embodiment of my invention shown and described is to be regarded as illustrative only, and it is to be understood that the invention is susceptible to 'varia tion modification and change within the spirit and scope of the subjoined claims.

"Having described my invention, I claim:

1. In a device of the class described, incombination, a platter having a depending flange,' a spider, and resiliently pressed means engaging said spider and said depend herein ing flange to hold said platter in place upon said spider.

2. In a device of the class described, in combination, a platter having a depending flange, aspider having outwardly extending arms adapted to engage the depending flange of said platter, and resiliently pressed means carried by said spider and adapted to co-operate with said outwardly extending arms to engage the depending flange to hold the platter in place upon said spider.

3. In a device of the class described, in combination, aplatter having a downwardl and inwardly extending flange, a spider having a plurality of outwardly projecting arms adapted to engage said flange, and means including a spring-pressed plunger adapted to engage the flange to hold the platter in place on said spider.

4. In a device of the class described, in combination, a platter having a downwardly and inwardly extending flange, a spider adapted to support said platter a projection on said spider having a bore, a plunger slidably positioned in said bore, and resilient means for holding the plunger in engagement with the depending flange oi the plan ter to retain the platter on said spider.

In a device of the class described in combinationa spider having a plurality of outwardly projecting arms, a platter having a downwardly and inwardly extending flange supported upon said spider, a projection on said spider having a bore, a

plunger slidably positioned in said bore and adapted to engage the flange on said platter, and means including an expansive spring engaging said plunger to resiliently retain the plunger in forcible engagement with said platter to hold same in place upon said spider.

6. In a device of the class described, in combination a spider, a platter having a depending flange supported upon said spider. a plunger slidably positioned in said spider and adapted to engage said flange, resilient means engaging said plunger to resiliently retain the plunger in engagement with said flange, and means including a stop member for limiting the movement of said plunger.
